How to Run a Python Bot 24/7

Python is renowned for its clean syntax and extensive ecosystem of libraries for building Discord bots (discord.py, disnake), Telegram bots (python-telegram-bot), web scrapers (BeautifulSoup, Playwright), and automated crypto/stock trading bots.

In this guide, we walk through setting up a virtual environment, managing dependencies, and hosting a Python bot 24/7 on your RivinCloud VPS.

1. Step 1: Install Python and Development Tools

On Ubuntu/Debian, install Python 3, pip, and venv:

sudo apt update
sudo apt install -y python3 python3-pip python3-venv git

Verify installed versions:

python3 --version
pip3 --version

2. Step 2: Set Up Project & Virtual Environment

Never install project pip packages globally across your operating system. Always create an isolated virtual environment:

mkdir -p ~/my-python-bot
cd ~/my-python-bot

# Create virtual environment named 'venv'
python3 -m venv venv

# Activate virtual environment
source venv/bin/activate

(Your prompt will now show (venv) at the beginning).

Install your dependencies:

pip install discord.py python-dotenv

Save package requirements:

pip freeze > requirements.txt

3. Step 3: Configure Environment Variables

Create .env:

nano .env

Add your bot credentials:

DISCORD_TOKEN=your_private_python_bot_token_here

Sample Python script (bot.py):

import os
import discord
from dotenv import load_dotenv

load_dotenv()
TOKEN = os.getenv('DISCORD_TOKEN')

intents = discord.Intents.default()
intents.message_content = True
client = discord.Client(intents=intents)

@client.event
async def on_ready():
    print(f'✅ Python Bot connected as {client.user}')

@client.event
async def on_message(message):
    if message.author == client.user:
        return

    if message.content == '!hello':
        await message.channel.send('Hello from Python 24/7 on RivinCloud VPS!')

client.run(TOKEN)

Command of the Day: python3

The python3 command invokes the Python 3 interpreter.

Syntax

python3 [options] [script.py]

Practical Examples

# 1. Execute script using active virtual environment interpreter directly
./venv/bin/python3 bot.py

# 2. Check installed modules
./venv/bin/python3 -m pip list

4. Step 4: Keep Python Bot Online 24/7 with Systemd

Create a dedicated systemd service to manage your Python bot:

sudo nano /etc/systemd/system/pythonbot.service

Paste the following configuration:

[Unit]
Description=24/7 Python Bot Daemon
After=network.target

[Service]
Type=simple
User=ubuntu
WorkingDirectory=/home/ubuntu/my-python-bot
ExecStart=/home/ubuntu/my-python-bot/venv/bin/python3 /home/ubuntu/my-python-bot/bot.py
Restart=always
RestartSec=5

[Install]
WantedBy=multi-user.target

Reload systemd daemon, enable on boot, and start service:

sudo systemctl daemon-reload
sudo systemctl enable --now pythonbot

Check live service status:

sudo systemctl status pythonbot

Common Mistakes

• Forgetting source venv/bin/activate: Installing packages without an active virtual environment leads to externally-managed-environment errors on newer Ubuntu releases.
• Relative file paths inside Python scripts: Opening local files (e.g. open('data.json')) fails if the working directory changes. Use absolute paths based on os.path.dirname(__file__).

Troubleshooting

• Check Live Systemd Logs:

  sudo journalctl -u pythonbot -f
  

Best Practices

• Always freeze requirements using pip freeze > requirements.txt.
• Use systemd or PM2 (via pm2 start bot.py --interpreter ./venv/bin/python3) for continuous uptime.

Frequently Asked Questions

Can I run Python bots with PM2 instead of Systemd?

Yes! Install PM2 and run: pm2 start bot.py --name "python-bot" --interpreter ./venv/bin/python3

Conclusion

Hosting Python bots with virtual environments and systemd services provides rock-solid 24/7 uptime on your RivinCloud VPS!
